ELECTRICAI LY DRIVEN AND MOVED PLOW.

SEECIFICATION forming part of Letters Patent No. 605,631, dated June 14, 1898. Application filed October 9, 1897. Serial No. 654,673. (No model.)

To all-whom it may concern.-

lle it known that I, ERICH DALLMANN, electrical engineer, a subject of the King of Prussia, Emperor of Germany, and a resident of Neusalz-on-the-Oder, in the Kingdom of Prus- 'sia, Germ any, have invented a certain new and .useful Electrically Driven and Moved Plow, of

which the following is a full and clear specifi- V cation My invention relates to an electrically driven and moved plow which differs from the devices hitherto employed by it in that the plowshares are supplied byaplural-ity of rota tin g conical screws which may be raised or lowered according to the wished for depth of fur rows. The rotating movement of those screws, as well as the; forward and backward moving .of the new govcrnablc plow-carriage, are effected by means of a sole motor. As the boring movement of the screws is beneficial to the forward moving of the carriage and to the a'horizontal section of one-half of the ma-- removing of the plowed ground, a considerable amount of power is spared'by employing those screws in the place of the hithertoused plowshares.

, Tn the accompanyingdrawings, Figure l is chine on line a: a: of Fig. 2, and Fig. 1 is a similar view of' the other half; Fig. 2, a vertical section of one half of the machine on line pg of Fig. 1, and Fig; 2 is a similar view of the remaining portion. I

The framing A, which bears the motor, with its reversing contrivance the (properly speaking) plow, and the guiding contrivance of the guidable plow-carriage, rests upon three wheels, the foremost-a of-which serves as a guide-wheel and is lodged in a fork a at the lower end of the vertical guide-shaft or. On thisguide-shaft'there is secured at the upper end a conical tooth-wheel b, which engages another tooth-wheel I), moved by'a-hand wheel a, so-that by turning the latter inone or theotherdirection the plow-carriage may beguided.

"M-otor'B drives by means of a suitable spur-- geara shaft d, which effectsthe back and forward moving of the carriage andlactuates pbelti i f in the meantime the rotating screws. The

former motion is transmitted by means "of a and thelatter by means of beltgearings D D. The forward and backward moving of the carriage is effected by insert ing a, simple reversible wheel-gear--such as. for instance, a double conical wheel-gearing. which may be reversed by means of a revc ing-lever t, as illustrated by the accompanying drawings.

The changing of the forward and backward moving of the carriage may as well be obtained by reversing the electromotor itself. The screws E E E E are lodged with their shafts g g g alternately and in such a manner as to be prevented from -conaxial shifting in frames F F, which are suspended pendulous behind each other .on the shafts c f, the latter being driven by the belt-gearings D D",.- The screw-shafts g g g g are driven by pairs of conical wheels 71,, secured, respectively, upon the upper ends of the screw shafts and upon the transverse shafts e and f. That mode of gearing has for its especial purpose that the axis of the shafts 9 may be more or less inclined as it may be needed for obtaining a given depth of furrows without detriment to the steady driving of the mechanism. The maneuver of all screws is effected simultaneously and in a uniform manner position at-the same time as they are dis" placed, there is arranged an adjusting device consisting of a vertical screw 70, lodged at the framing of the plow-carriage, so as to be prevented from conaxial shifting, upon which travels a nut Z, secured against turning and coupled to the foremost. frame F bya guide m. Screw 7r takes its rotary movementfrom a pair'of -conical wheels n, the one of which is fastened'at the top of the screw, while-the other is secured upon the hindmost end of a horizontal shaft 0, reaching unto the engine platform and which may be actuated by 5" means of aband-wheel of.

Tlieplow-carriage is entirely protected by 4 a roof G.

The. electric eurrentis conveyed to the motor by means of two rings 19 p, acting as ,slid- 10o ing contacts and secured at the top of a hollow post @q, fastened upon roof G and covered by.

i i i i i i i ing obliged furrows until the center another little roof Said rings are isolated as well from each other as from post q and take the current at their outer side from sliding brushes r a which. are fastened to a bow s, that may turn around post q. That arrangement labs for its purpose that the current may be conveyed to the motor while the plow is traveling around the field without beto displace the source of power placed in the center of the field.

When the plow-carriage is to be moved backward or when. it is to be driven over roads, the screws are raised-by means of the contrivanceherctofore described, so that they do not labor the ground. As it has already been stated at the beginning of the present statement the boring movementof the'screws is beneficial to the forward moving of the carriage and facilitates considerably the work of plowing as compared to the hithertoemployed plowshares.

\Vith the new plow plowing is'begun at a corner of the held and goes on by following spirally the borders of the same in parallel is reached, so that the plow-carriage needs only "to be guided at the corners, while for the rest it may continuously move on.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- I1. In an electrically drivenuand moved plow a guidable plow-carriageA, a plurality of shafts'c f arranged behind each other in the rear partof said carriage, frames 1* F pendulously suspended and devices for ad justing and securing them, shafts g lodged in said frames so as to be prevented from conaxial shifting and bearing firmly attached to their lower endconical plow-screws E, 'a conirivance for moving forwardly and backward! y plow-carriage A, which bears all parts of the plow, an electromotor B driving said carriage and actuating the plow-screws and means for conveying the electric current from a stationary source to the tially as and for the purpose set forth.
